Hoverboards are those gadgets that will forever be remembered for spontaneously blowing up and not actually hovering in 2015.
Franky Zapata at Zapata Racing wants to change this with his latest invention which is the closest thing yet to a real hover board. Details of how the Flyboard hovers is scarce but from the video it appears to be powered by a gas turbine engine and a man with a backpack full of petrol. That probably explains the need to test the device over water with Zapata himself donning a full fireproof suit.
